The family is all in with Beats Music subscription deal from AT&T.

AT&T has an exclusive Beats Music subscription deal that should sound good to families.

For a monthly fee of $14.99, AT&T family accounts can get unlimited music access for five family members on up to 10 devices. Families can sign up for a three-month free trial of the service when Beats Music becomes available in AT&T stores or online at att.com/beatsmusic on Jan. 24. Customers with individual AT&T accounts can opt for a $9.99 monthly deal on three devices.

The new Beats Music service launches Jan. 21 on the Web for computers and in app stores for Android, iOS and Windows devices.

Beats Music, says AT&T Mobility Chief Marketing Officer David Christopher, "has the ability to reinvigorate people's passion for music and do it in a way with accessibility that doesn't exist today."

The road to Beats Electronics, the company best known for its Beats By Dr. Dre headphones, creating a music service began nearly two years ago when the company acquired the online music service MOG. MOG was the first streaming service to make music available in the higher quality 320-kilobits per second format when competitors used 129kbps or 192kbps. Beats Music will offer 320kbps MP3s.

The new service has more than 20 million songs on board at launch. In addition to recommending new music to listeners based on their tastes, Beats Music also offers playlists curated by experts – some designed for moods and situations.

"Beats Music is the first music service that was built mobile first," says Beats Music CEO Ian Rogers. "We try to cover your tastes whatever those would be … including 'Where are you? What are you doing? What kind of music do you want to hear?' It's curated by human beings and it's personalized."

Users can stream music as well as download albums and playlists for offline listening. "The quality and premiumness of Beats Music will be unsurpassed," Christopher says.

Beats can lean on AT&T's reach to help lure subscribers. "We've got thousands of stores fired up about this service," he says. Spending some time with the service should make subscribing an easy sell after customers finish their 90-day free trial, Christopher says.

The AT&T-Beats relationship began nearly two years ago when he bumped into Beats co-founder Jimmy Iovine in Barcelona at the annual Mobile World Congress. "We have been really successful with family plans and after we saw the concept (for Beats Music) we began thinking how do we give the family premium music," Christopher says. "If you think about what else is in the marketplace, if your family wants streaming music … or downloads, it's hundreds of dollars of music a month.
